Based On The Above Track Record, ZENGKUN Is Able To Offer Expertise On Site (Grease Analysis, Videoscopy, Seals Replacement, Blade Bearing Inspection ), As Well As Blade Bearing Spares For A Wide Range Of WT.

The Blade Bearing Is A Rotating Joint Between The Wind Turbine Blade And The Hub And Is A Key Component In The Electric Pitch System.
The Blade Bearing Is Installed Between The Blade And The Hub, And The Inner And Outer Rings Are Respectively Coupled With The Blade And The Hub By Bolts, So That The Blade Can Rotate Relative To Its Axis To Achieve The Purpose Of Pitching.
Blade Bearings Are Mainly Subjected To Radial Loads, Axial Loads And Overturning Moments.
According To The Working Characteristics Of The Blade Bearing, The Blade Bearing Should Be Required To Have High Reliability, Flexible Operation, High Temperature Resistance, Cold Resistance, Sand Resistance And Corrosion Resistance.
Under The Condition Of The Environment, The Rated Life Is Up To 20 Years. At The Same Time, The Pitch Of The Blade Bearing Also Has Higher Requirements, And It Is Also Required That The Blade Bearing Should Have Good Sealing Performance. Blade Bearings Usually Use Double Row Four Point Contact Ball Slewing Bearing.

Yaw Bearing Is An Important Part Of Yaw System. It Is Located At The Bottom Of The Engine Room. It Bears All The Mass Of The Main Drive System Of The Wind Turbine And Transmits Aerodynamic Thrust To The Tower.
It Is Used To Adjust The Windward Angle Of Wind Turbine Accurately And Timely. Therefore, It Can Be Said That Yaw Bearing Is The Guarantee For Wind Turbine To Track The Change Of Wind Direction In Time.
In Addition, Because Wind Turbines Work In The High-Altitude Environment In The Field, Yaw Bearings Work In Sand, Rain, Salt Fog, Humidity And Other Environments, To Install, Lubricate And Maintain Them.
It Brings Inconvenience. Therefore, Yaw Bearings Are Required Not Only To Have Sufficient Strength And Load-Bearing Capacity, But Also To Run Smoothly, Safely And Reliably, Have A Long Service Life (Generally Required For 20 Years), Good Lubrication, Anti-Corrosion And Sealing Performance.
According To The Force Characteristics Of Yaw Bearing: Bearing Axial Load, Radial Load And Overturning Moment At The Same Time, Yaw Bearing Usually Adopts Single Row Four-Point Contact Ball Or Double Row Four-Point Contact Ball Rotary Slewing Bearing.
